I've gotten as far as finding x at least I think 10, -12...but I don't know where to go from there. :( Answer by checkley71(8403) (Show Source):
You can put this solution on YOUR website! (x+6)(x-4)=96
x^2+6x-4x-24=96
x^2+2x-24-96=0
x^2+2x-120=0
(x+12)(x-10)=0
x-10=0
x=10 meters is the length of the square sides.
PROOF:
(10+6)(10-4)=96
16*6=96
96=96
